Digestive System - Science

 Teeth 

How do these organs help our body digest food? 

It helps us by tearing the hard parts of our food. It chews our food and combines our food with saliva which turns it into Bolus. A term used to describe food that has been chewed.


Why are they important for our survival?

Your teeth are important for your survival because if you don’t have teeth, you have nothing to chew your food. 


Oesophagus 

How do these organs help our body digest food? 

After the food turns into bolus in your mouth the next process will be the contracting and squeezing the food together in your oesophagus. This will make the good moves down from the Oesophagus to the stomach.  


Why are they important for our survival?

This organ is important because they are helping us in the digestion process. If we don’t have this organ it can be hard for us to digest the food. 


Stomach 

How do these organs help our body digest food?

The stomach is one of the most important organs that is needed to be able to digest food. The stomach breaks down the food that you chewed and swallowed. The stomach’s strong muscles start to work and act like a blender which turns the bolus into a usable form.


Why are they important for our survival?

Like I said before, the stomach is an important organ in our body because it breaks down the food that you have chewed and swallowed. It then sends the ‘usable form’ into the small intestine and carries on from there.


Small Intestine  

How do these organs help our body digest food? 

Small intestine is helping our body to absorb the nutrients in the food. This organ is also carrying the most work for our digestive process. 


Why are they important for our survival?

As I said, the small intestine is the organ that does most of the work is the digestion process. 




Large Intestine  

How do these organs help our body digest food?

The job of this organ is to absorb the remaining nutrients, minerals and water in your body. This organ is also helping to change the leftover waste into bowel movements. 


Why are they important for our survival?

This organ is important because if we don’t have a large intestine we won’t be able to have water in our body. We all know that almost every part of our body needs water so we need an organ that can help us to absorb water. 


Liver 

How do these organs help our body digest food?

Liver is the organ that absorbs some of our body needs. One of the things that we need in our body that our liver is absorbing is fats. 


Why are they important for our survival?

Our body needs fat but not too much. So this is the reason why our liver is important for our survival. 


Rectum 

How do these organs help our body digest food?

The Rectum is filled with nerves that sense when it is full and when the body waist (poop) is ready to be evacuated. The waist stays in the rectum until the time comes for the evacuation.


Why are they important for our survival?

The rectum is important because it is the only organ that stores the waist until it’s time for the evacuation to take place. 


Anus 

How do these organs help our body digest food?

After the digestion process and the rectum is filled with waste it will come out into anus. Basically, that is what you call poo. 


Why are they important for our survival?

It is important to our body to let out the waste and we can get sick if the waste stays in our body.
